Nepal Airlines has an extensive network of air services to major parts of the country. Besides Nepal Airlines, other domestic airlines (there are more than 18 in operation) provide regular and charter services to popular domestic destinations. Many domestic airlines operate early morning, one-hour Mountain flights round the year.

Airport Tax: Airport tax is already included in the international air ticket; therefore, passengers departing for international destinations from the Tribhuvan International Airport in Kathmandu do not need to pay airport tax at the airport during departure. However, for domestic travel within Nepal airport tax is included in ticket fare for flights from Kathmandu, while for flights from other parts of the country one has to pay airport tax at the domestic airport before departure.
